Suzlon recently completed production of its first blade for its S111 2.1 MW turbine. The S111 is a technologically advanced product of the S88 and S97 2.1 MW family. This product has been specifically designed for Suzlon’s next generation 2.1-MW turbine and is engineered to deliver a 62% increase in AEP (Annual Energy Production) at 120m hub height compared to Suzlon’s S88 wind turbine model.
The S111 is built on the proven reliability of the S88 and S95/97 2.1 MW family that currently has over 3100 turbines installed in fifteen different countries with over 68,000,000 operating hours. The blade is designed to harness the optimal available wind resources and deliver higher energy productivity, which in turn ensures higher ROI to customers.
“The first SB54 blade is the longest and cleanest aerodynamic profile Suzlon has ever produced,” says Laurens van der Sande, project manager. “This milestone has been achieved due to an effective integration between the product design, production unit and the tool design. The result is reflected in a shorter production timeline with a high yield product.”
The turbine design makes it ideal for low wind sites in growth markets like the U.S. and India,” says Tulsi Tanti, Suzlon chairman.
The first S111 turbine prototypes are being assembled and will be erected and tested later this year in India and in the USA. Certification is expected in the first half of 2015.
